THOMAS HARPER, OF XVESTCHESTER, ASSIGNOR TO JOHN HARPER, OF EROOKLYN, NEV YORK.

TYPE FOR 'P RINTING LAMP-SHADES.

fSPECIPICATION forming part of Letters Patent No. 454,868, dated June 30, 1891.

Application filed August 20, 1890. Renewed May 25, 1891. Serial No. 393,941. (No model.)

To aZZ whom, it may concern.-

Be it known that I, THOMAS HARPER, a citizen of the'United States, and a resident of lVestchester, in the county of lVestchester and State of New York, have invented certain new and useful Improvements in Type for Printing Lamp-Shades and Analogous Articles, of which the following is a specification.

The object of my improvement is to provide a simple and inexpensive type which will present a substantially fiat surface for inking,'and will yield to adapt itself to the convexity of a lamp-shade or like article.

I will describe type embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure 1 is a face view of a type embodying myimprovement. Fig. 2 is a sectional side view taken principally at the plane of the dotted line 0000, Fig. 1. Fig. 3 is an end view of a socket comprised in the same.

Similar letters of reference designate corresponding parts in all the figures.

A designates a printing-surface consisting of a piece of india-rubber, rubber cloth, or othersuitable flexible material out to a shape resembling some article or thing.

B designates a support for the printing-s urface. It consists of a number of elbow or boll-crank levers 1) b fulcrumed upon rods 1), which are secured in a frame 6 The frame If is secured to the upturned extremities c of two rails c 0 forming part of a holder C. This holder 0 has a socket D, whereby the type may be fastened to a movable arm in a printing-press. This socket has a longitudinal opening, and adjacent to this opening is provided with two lugs cl (Z A screw (1 assin loosel throu h the 111 d. and en a p O y D h b 2) ing with a tapped hole in the lug (1 serves to tighten the socket upon the arm to which it is applied.

The outer arms of the levers b b are intended to be normally in the same plane, and while they arein the same plane the printingsurface A will be flat and in condition to be properly inked. Springs b are applied to the rearwardly-extending arms of the levers for the purpose of maintaining the outer arms of the levers in the same plane under ordinary circumstances, and for returning them to such posit-ion after they shall have been deflected therefrom. As here shown,thereis a lever 5 immediately opposite each lever 19', and a spring I), connecting the rearWardly-extending arm of each lever b and the corresponding arm of the opposite lever 17. Stop-pins b may be used to prevent the springs Z from carrying the levers Z9 12 into such positions that their outer arms will project outwardly, so that these arms of the levers I) will be out of line with the corresponding arms of the levers b.

The printing-surface will preferably be attached only to one of the leversas, for instance, to the center lever 19 It may be attached thereto by cement, as at 3. Then only attached to one of the levers it will be free toslide overthe others, and hence it and the levers can the better conform to convex surfaces.

It will be seen that the support B is much larger than the printing-surface A. This is to render the employment of larger printingsurfaces possible.

WhatI claim as myinvention, and desire to secure by Letters Patent, is-

l. A type having a priutingsurface, and a support therefor, consisting of a number of levers arranged in rear thereof, substantially as specified.

2. A type having a printing-surface, and a support therefor, consisting of a number of levers arranged in rear thereof and springs for adjusting the levers into position to hold the printing-surface flat, substantially as specified.

A type having a printing-surface, and a support therefor, consisting of a number of bell-crank or elbow levers b b and springs 19*, connecting the levers Z) If in pairs, substantially as specified.

Signed at New York, in the county of New York and State of New York, this 12th day of May, A. D. 1890.

THOMAS HARPER.
